That's why G*d invented RTP, of course. And all of these buses are "slow" by the time they're popular enough to worry about. In any case, delete the "ethernet" part if you want to still play with the mac/phy.
Well, the reply was sent in response to somebody talking about HDMI. HDMI 1.4 can carry over 8 gigabits per second, so to re-use ethernet PHY (and still be copper) you'd have to go with 10GBaseT. The cheapest 10GBaseT card I see at a glance is over $400, while I can find Blu-Ray players with HDMI 1.4 (and oh yeah, an optical drive, video decoder, etc.) for under $100. I'm sure some of that price difference is related to manufacturing volume, but I don't think it is that big of a percentage. I will say that one nice thing about having different connectors for different protocols (on consumer devices anyway) is that you don't have to worry about somebody plugging the Internet into the "Video 1" port and wondering why they aren't getting a picture. -- Chris Adams <cmadams () hiwaay net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.
